Recently, the open source software market is becoming bigger and bigger as its demand keeps increasing worldwide. A variety of policies have been driven in Korea in order to vitalize the open source software. However, the performance for vitalizing the open source GIS software has not been initiated yet. The purpose of this research is to generate the support plan to vitalize the domestic open source GIS software which is appropriate for real field by analyzing the actual demand and user requirements. For this purpose we reviewed all the researches related to the vitalization of the open source software and conducted a survey based on the awareness of the open source GIS software, the current vitalization status, the adoption intent and necessary strategies for vitalization. According to the survey, the intent of adopting the open source GIS software is relatively high in both enterprises(97%) and universities(89%). On the other hand it is very low in public organizations(69%). As a result, the survey implies that more intense public relations are needed to escalate the awareness of the open source GIS software in the public organizations. In addition, the survey shows that both education and technology support are definitely needed as a strategies for the vitalization of the open source GIS software. We expect that this research can be utilized as a basic material for the policy making of the vitalization of the open source GIS software in Korea in the future.

These days open source softwares are being introduced and applied in many countries in the world. Especially, both government and private companies tend to become an spearhead in vitalizing the open source software. In this paper we try to check the degree of vitalizations in open source GIS software and to draw implications in vitalizing ecosystem of open source GIS software. Key players of open source GIS software ecosystem are government, private companies, academic and research institutes, and nonprofit foundations. Government does not have very little policies related to the investment and the support of open source GIS software. Private companies related to the open source GIS software are very few in the number and do not have any clear business model to make a profit. Academic and research institutes are weak in using the open source GIS software, which can be an major obstacle to cultivate software developers. OSGeo Korean branch, established in 2009, is the only nonprofit foundation in Korea which makes an effort to vitalize the open source GIS software, but its results are not very strong up to now in view of both quality and invigoration. In order to vitalize the open source GIS software ecosystem, lots of efforts of key players are needed. Especially, government efforts are very important because it can provide a trigger in vitalizing the open source GIS software ecosystem. The tasks that government should propel are R&D investment, test bed projects in the area of public sector, professional manpower training, and international cooperation and marketing.

The purpose of this study is to propose an open source GIS software business model for the revitalization of Korean open source GIS software industry. In this study, we categorized the types of open source software business models and developed an open source software business strategy suitable for GIS companies in Korea. To propose a business model, we applied the business model canvas which is often used in the area of business studies to analyze new business models. We tried to develop the open source GIS business model through both interviews and case studies with Korean open source GIS software companies. We propose three different types of open source GIS software business models such as distributor model, producer model, and 3rd party service provider model as follows: first, the companies which belong to distributor model can carry out business by providing professional services in the market of open source software. Second, the companies which belong to producer model can sell their products to the global market as well as the domestic market. Lastly, given the growing interest in domestic open source software, the number of third-party service providers is likely to continue to increase in the future. Therefore, it is expected that the companies which belong to the third party service provider model will be able to develop various business models by securing the technology.

The 'Open Source' of programing is a method that is not only sharing the source, but also making the S/W by the low cost and easy way. In this study, we made the urban facilities management system(FMS) based on the GeoFOSS of Open Source. This system has the GIS function of the urban facilities management, the u-GIS function using the USN for processing the spatial information. Also, as we use the GeoFOSS of 'Open Source', we can have received many benefits. First, this system has the economic impact, because it is not necessary to buy the commercial GIS software. Second, this system can make most functions of the GIS, the performance does not bad compared to other products. Also, this system strictly conforms to the international standards, it is easy to get a repair, maintenance and interoperability.

A Tile Map Service is a regular map service that has been enhanced to serve maps very quickly using a cache of static images. The map cache is a directory that contains image tiles of a map extent at specific scale levels. Returning a tile from the cache takes the server much less time than drawing the map image on demand. Use of a Tile Map Service can dramatically improve the time that clients take to display complex base-maps. Using Tile Map Services thus eliminate the need to trade quality for performance. This study provides a way to construct Tile Map Service System using Open Source GIS. We used GDAL(Geospatial Data Abstraction Library) which is one of the Open Source GIS Softwares to make Tile Map Image and OpenLayers to publish Web Page. Moreover, We conducted a performance test on Tile Map System and Dynamic Map System and evaluated the results of it. As a result, the proposed method makes it easier to construct high performance Tile Map Service using Open Source GIS without commercial products.
